IMPROVEMENT IN COAL-HOISTING APPARATUS.

Specification forming part of Letters Patent No. 185,255, dated December12, 1876; application filed October 7, 1876.

To all whom it may concern:

Be it known that I, GUIsEPPE PAOI, of the city, county, and State of NewYork, have invented a new and Improved Apparatus for Hoisting Goal, ofwhich the following is a specification In the accompanying drawing,Figure 1 represents a side elevation, partly in section, of my improvedapparatus for hoisting coal and other articles. Fig. 2 is a sectionalend view of the same, and Fig. 3 a detail sectional side view of thebucketconveying carrier.

Similar letters of reference indicate correspondin g parts.

The object of my invention is to furnish an improved apparatus for thepurpose of hoisting coal, bricks, and other articles from vessels orother places directly into the carts or other vehicles, by utilizing thepower of the horse or horses pulling the same for hoisting the coal,&c., in economical manner, so as to obtain the direct transfer of thearticles, and dispense with a special horse, steam-engine, or otherpower for hoisting.

The invention consists of an inclined endless belt, with step-shapedparts, to be operated by the cart-horse for rotating a drum, on whichthe hoisting-rope is wound. The cord runs over guide-pulleys of asupporting-frame and of a bucket-conveying carriage, that locks andunlocks a fixed button in automatic manner to convey the load or lowerbucket. The work of the endless stepping-belt is stopped or interruptedby a lever actuating a double clutch and brake mechanism of thewindingdrum shaft. A weighted lever and swinging hub-locking standardsecures the cart or vehicle in stationary position for hoisting actionof horse.

In the drawing, A represents an endless belt, that is stretched overtoothed spider frame-wheels B, which engage intermeshing projections ofstep-shaped parts a, connected by suitable pivot-links. The steps a arepreferably made of sustaining or stiffening frames, of cast-iron, andwooden facings, so arranged that the horses find a good foot-holdthereon. The endless stepping-belt is arranged at such inclination onthe wharf or other place where the hoisting apparatus is to be used thatpart of the belt is below and part of the same above the level of thewharf. The steps a arealso arranged at a small angle of inclination tothe supporting-chains, for the purpose of providing, as near aspossible, a horizontal support or rest for the feet of the horses. Thecart or other vehicle is guided by rails bearing at the inside of thewheels to the belt, the horse or horses stepping on the same, being thenin position to work the same. The vehicle is locked into rigid positionon the wharf before the horse begins to work the belt by means of astandard, 0, at one or both sides of the guide-track, the standard beingprovided with a recess, I), for fitting over and binding on the hub ofthe vehicle. The standard G is hinged at the lower part to the wharf,and operated by a crank-rod, d, and lever d with weighted handle d so asto be readily released from the hub. A curved guide-piece, e, at theupper part of the standard U, sidewise of the hub-recess b, serves tothrow the standard 0 sufficiently back by the hub that the vehicle maypass on and be locked automatically by the standard and the weightedlevers 01 d On the shaft of the stretching-wheels B, below the level ofthe wharf, is placed loosely a winding-drum, 1), for the hoisting-ropeE. The winding-drum D is thrown into or out of gear with its shaft bythe double clutch f. The clutch f is operated by a fulcrumed lever, f,that engages, by its lower semicircular end, the grooved slidingclutch,being set, by its upper handle end, into a notched lock-bar, f for thepurpose of securing the clutch to the winding-drum, or applying a brake,f connected to the lever f and acting on a fixed pulley of the drum, orfor throwing the clutch entirely out of gear with the drum for admittingthe unwinding of the hoisting-rope. When the lever is applied to thesecond notch of the lock-bar, the rotation of the drum and of theendless belt is interrupted, and the load of the hoistingrope retainedat the required point. The hoisting-rope E passes over pulleys of astationary or movable frame, F, secured to the wharf, and arranged toproject beyond the same, so that the bucket applied to the end of thehoisting-rope may readily be lowered into the boat or other vessel. Thehoistingrope E passes also over a pulley of a carrier,

F, that moves on inclined ways of frame F,

and serves to convey the bucket along the inclined way. The carrier F isprovided with two V-shaped pivot-levers, g 1 of which one has ahook-shaped upper arm, while the other lever has a hook at the lowerarm, its upper arm being weighted. The pivoted lever 9 looks the carrierF, by its hook end, to a pointed or tapering stop-plate, 1 at the lowerend of the inclined way, while the second lever, g hears, with its upperweighted part, on the inclined stop-plate 9 so as to raise the lowerhook end clear of the pulley. To the hoisting-rope E is attached aconical button, h, at the required distance above the bucket, whichbutton strikes against the lower ends of both pivot-levers, producingfirst the locking of the longer hook-arm of the weighted lever g overthe base of the button, and then' the raising of the other lever bycontact with the shorter lower arm of the same, as shown in detail inFig. 3, so as to produce the unlocking of the carrier and the travelingof the same, with the bucket suspended therefrom, along the inclined wayof the supporting-frame E. The button It may be adjusted at any suitablepoint on the rope, as it is made of two detachable parts-a conical shankand the disk-shaped base-which are screwed together. By unscrewing theparts and sliding the shank along the hoisting-rope, and forn1- ing aknot between shank and base, and finally connecting the parts, thebutton may be rigidly affixed at any part of the rope. When the bucketarrives at the point above the cart the carrier is locked by the clutchand the bucket emptied. The clutch is then released entirely. from thewinding-drum, and the carrier and bucket thereby allowed to descend onthe inclined way till the lever-hooks form contact with the stop plate,so as to release the button and lower the bucket into the vessel.

The cart-horse is thus used, while being harnessed to the cart, forhoisting the load into the cart, dispensing with extra power, the cartor vehicle being released from the hub-standard when loaded, and thehorse allowed to pass over the belt and an inclined plane at the end ofthe belt directly to any point of storage, forming thus a convenient andeconomical means of hoisting and conveying coal and other articles fromvessels.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- 1. An improved apparatus for hoisting coal and otherarticles from the vessels, consisting of an inclined endlessstepping-belt with winding-drum, hoisting-rope, and bucket-conveyingcarrier, and supportingdtame, substantially in the manner and for thepurpose specified.

2. In an apparatus for hoisting coal, a swingin g standard, operated byweighted lever, and having recess to lock to hub of vehicle, forutilizing power of horse on stepping-belt, substantially as specified.

3. The swinging-and hub-locking standard 0, having curved guide-piece eto lock automatically to hub, substantially as set forth.

4. The combination of hoisting-rope E, having fixed button It, carrierF, having pivoted and weighted lever-hooks g g and stop-plate g of frameA, to release or look carrier from stop-plate of frame F, substantiallyas specifled.
